PHOTO GALLERY: Ashlee Simpson’s Lingerie Party

We know it’s been unseasonably warm in Los Angeles this week, Ashlee Simpson, but please—show some decorum!

The current Melrose Place actress made the scene at a lingerie-line launch at Coco de Mer on Wednesday night—where David Hasselhoff and his daughter were also in attendance—showing off her impressively lean post-baby body in an outfit that pretty much starved the imagination. 

Is she taking fashion tips from Lady GaGa now?
